AC problems on 2007 X5.. FSR

[freshwater]

I am trying to find a video or pic illustrated procedure to replace the FSU/FSR .
Google everything but they have for E39 and X5 2006 models not 2007 E70.

having problems not blowing enough Cold Air when AC is engaged, if I disengage AC then the AIR blow very fast from front vents, freon looks OK and I even fill some more.
Having this issue for almost 1 yr now. Air is cold but not blowing enough ..
Thinking that my AC Blower Resistor need replacement.. but without AC the Air comes out super fast ?? hope its the FSR nothing else..

I know its under the passenger side Glove compartment but cant locate it correctly.

PN = 64 11 9 265 892 from Valeo..

Thanks.
